Simple Simon at a glance
Simple Simon is played alone with a deck of 52 cards, all dealt face up across 10 columns: the first three receive 8 cards, then each column receives one fewer, down to the last, which has just one. There is no stock and no hidden card: everything is visible, everything can be planned.
Place a card on a card one rank higher, regardless of suit: a 7 on a 8. But a group of cards can only move together if it is of a single suit. The goal is to build a complete run from king to ace of the same suit in a column: it is then removed from play. The game is won when all 4 runs have been removed. The rules detail each move, and the strategy explains how to approach the game.
